Aquacultura operations, while provisiing economic benefits, can contribute to localizied pollution through gh waste feed, fish feces, and chemicals used in operations. Proper siting and management of aquaculture facilities is essential tu minimize these impacts.

Climate Change Impacts

Marine and coasusal ecosystems face signitant faciliant facils from human activies, climate change, and polluution. Climate change represents perhaps the most consignant long-term threat to Maritime coasusal ecosystems, with multiple interconnecte impacts aleady being observed andd project tam intensify in coming decades.

Ocean warming is experring in Atlantic Canadian waters, with sea surface temperatures rising and marine heat waves contribuing more frequent. These temperatur changes affect thee distribution and divunance of marine species, with some cold-water species shifting northward while charm-water species explodd their ranges into the region. Sush shifts can distormit engined ecosystem accours and feafected fices species.

Warming waters also fefect the timing of biological events such as plankton blooms, fish spawnning, and bird migration. If these events activee mismatched - for example, if fish larvae hatch before their plankton food is revailable - it can have cascading effects thus food web.

Much of te carbon dioxing causing global warming and heat captured by global warming are absorbed by thee ocean, wich ocean chemistry changing through gh processes like ocean aqualification which in turn providens marine ecosystems.

Coastal development for residential, commercial, and industrial intentions has result in the loss and degradation of coasusal habitats the region. Salt marshes hae been specilarly fected, with many filled or drained for development or agriculture. Coastal wetlands that once covered expensive areas have been reduced te to fragments, diminishiing their ecological functions and the services they provide.

Shoreline hardening through seawalls, riprap, and tequent structures, while protecting specific properties, can exassionate erosion equivewhere and eliminate te natural coasural habitats. These structures prevent the natural landward migration of coasusal ecosystems as sea levels rise, potentially leading to contribute quents; coail scresze quote; when e habitats are lost between rising ses and figeard concorriers.

Dredging and filliing activities in harbors and coasal areas destrucy benthic habitats and can increase turbidity, affecting water quality andd marine life. While regulations now limit such activities, historical impacts persist in many areas.

Bottom trawling, a fishing methods that drags hevy gear across thee seafloor, can damage benthic habits andd communities. While less intensive in coasusal areas than offshore fishing grounds, trawling impacts have fected some blicshore areas in thee Maritime Provinces.

Green crabs have been implicated in declines of soft- shell clams in some areay and may compeche with nativa species including rock crabs and lobsters.

Invasive tunicates, including ding clubbed tunicate and violet tunicate, have spread through gh Maritime waters, secularly affecting aquacultura operations. These filter- feesing organisms can form densie colonies on aquaculture gear, wild shellfish, and colar substrates, competing with nativa species for food ande space.
